The clause defines the operational duration of data retention and establishes user-initiated deletion as the mechanism for terminating storage. This determines the period during which Mistral AI maintains access to conversation data for service administration and any other authorized uses.
The updated policy now explicitly includes data accessed through third-party services and integrations users connect to Mistral AI Products as 'Input' data subject to collection and use. The policy removed its prior statement that Input and Output data are not used to train AI models when using Le Chat Enterprise or paid versions of Mistral APIs. This creates operational ambiguity: users of paid services and Enterprise customers no longer have a documented commitment that their data will be excluded from model training, though the privacy policy does not affirmatively state that model training now occurs. The policy also changed language describing product improvement from 'aggregated and anonymous statistics' to 'aggregated or anonymous datasets or statistics,' broadening the stated scope of what can be collected for improvement purposes.
